To all whom 'it may concern: v

.Be it known that l, DnNNrs HALnonAN, a subject oi' the King of Great Britain7 and a resident o1' Paris Station, Province of Ontario, and ADominion oi Canada, have invented a new and Improved Low-Lift Plow, oi which the following is a full, clear, and exact descrip- OIl. I

This invention relates to low lil't plows, and has for its object tg provide means adapted. to enable the plow to make a short turn; to permit the plow`to be readily adjusted so as to regulate the depth of cut, to regulate the width of cut-oi the furrow; to enable the plow to be readily lifted out ol the ground or placed therein; to enable the rear furrow wheel to be locked in position or allowed to run free at will, and to provide means whereand special arrangement of the several parts of my in-l vention will be understood by the following description and accompanying drawings, in which drawings `like characters oi reference indicate like parts throughu out the views, and in which Figure l is a perspective view'oi a plow embodying my invention; Fig. 2 is a side elevation of the upper rear portion of the plow beam with adjusting mechanism Vconnected therewith; Fig. 3 is a perspective view of a yoke' adapted to lock the standard of the rear furrow wheel; Fig. 4' is an end view of an adjusting lever attaeliedfto lthe plow beam, shown in cross section, with an auxiliary lever'connected therewith, taken on the line 4-4 of Fig. 2; Fig. 5 is a plan of the main frame of the plow shown in Fig. l; and Fig. 6 is a vertical transverse section taken on the line 6-43 of Fig. 5.

As illustrated in the drawings, the plow beam is pivotally connected with a transverse frame, which is mounted upon a land wheel l and furrow wheel 2, hav-l 'ing axles 3 and 4 connected with said wheelsrespec-` tively. The land wheel l is mounted upona spindle 5 ixedly attached to an arm 6,whch arm is journaled' upon the axle 3 in any suitable manner. Af notched segment 7 is iixedly secured to. the 'axle 3 by rneans of a set screw 8 or otherwise. A. lever 12 is also jouinaled upon the axle 3, and is connected with .the axle arm 6 by means oi a bolt 9 extending through a spiral spring l l0,r as shown in Figs. Vl and 5,. By means of such conv struction the arm 6 is rocked on the axle 3, as may be desired, so as to regulate .the depth-oi the furrow to be cut. The lever 12is locked in engagement withl the segment 7 and consequently with the axle 3, by ineans of a spring-actuated latch l1 provided with a grip arranged in' convenient relation with the upper end or lhandle of the lever 12. The axle 3 is journaled at one end' in an arm 13 (ixedly secured to the end of the axle 4, asshown inFig. 5, the axle being preferably made 'llate'nted July E0, F30?.

angular in cross section. The other end ol 'the 3 is end oi the lever being provided with va pin il@ engaging a horizontal slet 15@L formed in a bracket l5, which secured to the axle ,l and is connected by means of a upon the plow beam 22. 1i. notched segment 23 is also attached to the plow beam 22, and cooperates with a hold the lever 2l in a set position on the plow beam. A stub axle 17 is attachedto the bracket l5 and has its bearing in the furrow wheel 2. This furrow wheel is to climb, owing to the team walking unevenly. By Jmeans oi such cohetruction the-lever 2l, when moved cruined -in the bracket l5, by means of the crank pin vla engaging the slot l5E of the bracket 15, and thereby 13, and also by means of a traveling head mounted upon said axles and consisting of socket heads 3l. and 32 having bearing for the iixed and rocking axles respectively. v

A turntable is mountedriipon thetraveliiig head and is adapted to support the plow beam so as to enable the plow beg/n1 to be raised and lowered with the axles and thereby move the plow. 25 in and out of the 'ground lengthwise of the axles so as to adjust the vfidtlrof furbeam on said head, The turn table consists of abear ing plate 26, having. avcrtical -tlange 27 which is ixedly secured to the plow beam 22 by means of bolts 28. The

adapted tp slide on the axles 3 and e. A bolt 29 and washer 29' clamp the bearing plate and'baseplate of the turn table together.

The bearing plate 2G is provided with a lip 26a adapted to move in an are-recess 30a formed in the base plate 30, vso as to limit the movement of the bearing plate 26 on the base plate 30.

The base plate 3G is provided with a rearward extenplate 30, as illustrated by. dotted lines in Fig. 5. The latch 34 is held in the notch of ibase plate 30 by means voa sprinf- 34 secn'red'to the extension of the rod 20 with an operating llever 2l pivotally mounted backward or forward, rocks the axle 3, which is ulraises or lowers the axle 3 and also the angular axle 4. which is connected with the axle 3 by means of the arm when desired, and enable 'the plow beam to be movedI provided with a lever le lixedly secured tluereto, the l has a sliding engagement 'with a plate 16 xedly attached to the angular aigle 4. An arrn 19 is also rixedly spring actuated latch 2i oi' ordinary construction to staggered so as to permit the rim of the wheel to 'run in Y the angle 'of thefurrow where the ground is hard, and l Arelu ve the rim from rubbing againstthe'edge oi the". l furrow and also to prevent any tendency of the wheel. l

row and also permit a pivotal. movement of the plow bearing plate is preferably provided with a central apl ertu-re engaging a 1nnb 30 formed on' a base plate-.30 mounted upon a head of any suitable construction los lori

sion 33 having a bearing fora latch bolt 34 adapted to enage at its iorward end with. a notch. 30J formed in the plate'Sl). A eonnectingrod extends from the latch 4,
